The problem is its hard to tell what’s an ad and what’s not. Sometimes people ARE just enthusiastic about a product they found and want to share it.
It’s easier when it’s a large company like Burger King or something; like most people won’t just suddenly start raving about this great new burger place they found called Burger King. It’s different for more obscure companies. It could be actual Lemmy users who are just passionate or it could be company employees trying to sneak advertisements into site discussions.
I don’t think there’s any AI or other tools that could distinguish the two.
